Overview

Abdominal CT scan may be helpful in the diagnosis of gastrointestinal stromal tumor.

CT scan

Appearances vary with size and location. Typically the mass is of soft tissue density with central areas of lower density when necrosis is present (usually in larger tumours). Enhancement is typically peripheral (due to central necrosis). Calcification is uncommon (3%). Metastases (distant, peritoneal, omental) or direct invasion into adjacent organs may be seen in more aggressive lesions. Lymph node enlargement is not a feature.[1]
